Exam Prep Strategies That Actually Work

A lot of common study habits (highlighting, re-reading notes, marathon cramming sessions) feel productive but are among the least effective ways to actually retain material. Here's what the research on learning consistently supports instead.

Active recall beats re-reading

Re-reading a chapter feels like studying, but it mostly builds familiarity, not retrieval ability, the thing you actually need on exam day. Active recall means closing the book and trying to reproduce the information from memory: answering practice questions, explaining a concept out loud without notes, or writing down everything you remember about a topic before checking what you missed.

It feels harder than re-reading, and that difficulty is exactly why it works better: the effort of retrieval is what strengthens memory.

Spaced repetition beats cramming

Reviewing material once, right before an exam, produces short-term recognition that fades fast. Spacing your review sessions out over days and weeks (revisiting a topic just as you're starting to forget it) builds much more durable memory. A rough rule of thumb: review new material within a day, again after about a week, and again after a few weeks.

This means your revision schedule should start well before the exam, not compress into the final days beforehand.

Practice under exam-like conditions

Doing practice questions under time pressure, without notes, in a format close to the real exam, does two things cramming doesn't: it builds retrieval strength, and it surfaces exactly which topics you're weak on while there's still time to fix them. Save at least some practice tests for close to the actual exam date, done under real time constraints, rather than using them all early with unlimited time.

Interleave topics instead of blocking them

Studying one topic exhaustively before moving to the next (blocking) feels organized, but interleaving (mixing related topics or problem types within a single study session) better mirrors how you'll actually need to apply knowledge on an exam, where you don't know in advance which type of question is coming next.

Build a schedule you can actually sustain

An ambitious revision plan you abandon after four days is worse than a modest one you follow for six weeks. Build in rest days, and treat consistency as more important than intensity: an hour of focused active recall most days beats an unsustainable 6-hour session once a week.

Test yourself on explaining, not just recognizing

If you can recognize a correct answer in a multiple-choice question but can't explain the concept from scratch, you likely don't understand it well enough yet for questions that require application, not just recognition. Regularly test yourself by explaining topics in your own words, out loud or in writing, without referring to notes.
